CAMERA ATTACHMENT.

SPECIFICATION forming part of Letters Patent N 0. 733,292, dated July'7, 1903. Application filed December 15, 1962. Serial No. 135,271. (Nomodel.)

The object of this invention is 'to provide a hood which may beconveniently applied to a camera and used effectively to take the placeof the usual focusing-cloth.

To this end the invention comprises certain novel features ofconstruction which enable the attachment to be permanently connectedwith the camera and yet thrown into open position whenever it is desiredto reach the interior of the camera for adjustment or other purposes.

This specification is a specific description of one form of theinvention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in'both the figures.

Figure 1 is a side elevation with parts in section, and Fig. 2 is aperspective view showing the attachment in an open position.

The attachment comprises a main framesection a, which is rectangular inform and adapted to fit firmly against the focusing end of the camera.This frame-section is provided with a beading a, passing around itsforward edge and adapted to engage the cam-, era to make a light-tightconnection.

a indicates brackets which are fastened to said frame-section a andadapted to carry screws for connecting the frame-section with thecamera. Connected by hinges I) (see dotted lines in Fig. l) is aswinging framesection b, which is rectangular to match accurately withthe section a and which is adapted to engage a head 0, passing throughthe inner side of the frame-section a and pro jecting rearward beyondthe edge thereof, this bead a forming a light-tight connection betweenthe two; frame-sections a and b. b indicatesfa latch of any convenientform for removably holding the free end of the section b connected withthis section a.

An accordion hood d is attached to the frame-section b and tapersrearward, as illustrated, this hood carrying at its rear end a wall e,having an opening therein and around whichextendsashadef.Thisshadeisshaped to fit snugly against the face of the photographer, sothat he may look through the hood without admitting light thereinto. Forsupporting the hood to move in and out and for holding it at the desiredposition I employv at each side thereof a lazy-tongs g, one end of eachof which is connected with the section 17 and the other ends of whichare connected with extensions e of the end wall 6. These lazy-tongsallow the hood to be contracted or extended at will, and said lazytongsare rendered rigid to hold the hood at the desired adjustment by meansof guideplates 71. These plates are one for each lazytongs, and one endof each plate is pivotally connected to a pivot between two links of thetongs, said plate extending across the tongs and having its other endslotted, as indicated at h, to receive the opposite pin loosely therein.

7L indicates a thumb-nut for clamping the parts h and g rigidlytogether. It is clear that by this means the lazy-tongs may be lockedrigidly in the desired adjustment.

In using the invention the brackets a are fastened to the rear side ofthe camera, and after the camera has been properly adjusted theframe-section b is thrown to the closed position and held thereat by thelatch 5 The hood cl is now adjusted, the extensions 6 being orificed, asindicated at 6 thus furnishing convenient hand-holes for thephotographer. In adjusting this hood the end wall'e should be placed atproper focusing position, and when this has been effected the thumb-nuts77. should be tightened, thus rendering the tongs g rigid and preventingthe hood d from moving out of the adjustment to which it has beenplaced. The photographing operation may now be carried on convenientlyand without involving the many disadvantages of the well-knownfocusing-cloth. When the camera is not in use, the hood and its attachedparts may be folded snugly against the rear side thereof, and thereforethey will not materially increase the size of the camera.

Various changes in the form, proportions,

and minor details of my invention may be resorted to without departingfrom the spirit and scope thereof. Hence I consider myself entitled toall such variations as may lie within the scope of my claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A camera attachment comprising a main framesection, a swinging frame section hinged thereon, a latch for removablyholding the swinging frame-section engaged with the main section, a hoodcarried on the swinging section, means for extending said hood to apredetermined position, and means for looking the hood in said position.

2. A camera attachment comprising a main frame section, a swinging framesection hinged thereon by vertically-disposed pivots, a latch forremovably holding the swinging frame-section engaged with the mainsection, an extensible hood carried on the swinging section, expansiblemeans for moving the hood into a desired position of extension, meansfor locking the expansible means, and a bead extending around the mainsection and projecting from the rear edge thereof, said bead beingadapted to be engaged by the swinging section to form a light-tightconnection between the hood.

8. A camera attachment comprising amain frame-section, adapted to befastened to the camera, a swinging frame-section hingedly mounted on themain frame-section, said sections meeting each other edge to edge, abead mounted over the meeting edges of said sections to form alight-tight connection between them, an extensible hood attached to theswinging section, an end wall at the outer end of the hood, and meansvconnected with the end wall and with the swinging frame to adjustablyhold the hood.

4. A camera attachment comprising a framesection, an extensible hood, anend wall at the outer end of the hood, said wall having an openingtherein to permit observation through the hood, lazy-tongs connectingthe two ends of the hood, a slotted bar ext-ending across the tongs andhaving sliding connection with one side thereof, and a set-screwextending through said slot and engaging with a portion of the tongs forlocking the latter against expansible movement.

5. A camera attachment comprising an extensible hood, means for mountingthe same on the camera, an end wall at the outer end of the hood, saidwall having inner extensions forming hand-grips and a central openingforming an observation-opening through the hood, and means connectedwith the handholes adjustably to hold the hood.

6. A camera attachment comprising an extensible hood, means for mountingthe same on the camera, an end wall at the outer end of the hood, saidwall having inner extensions forming hand-grips and a central openingforming an observation-opening through the hood, and means connectedwith the handholes adjustably to hold the hood, said means being inconnection with the extensions of the end wall and lying at one side ofthe hood.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
